St. Petersburg High School Enrollment vs. Graduation Rate

Each district strives for a 100 percent graduation rate.

As students begin ninth-grade they become part of a "cohort" of students. Those who transfer to different districts, enroll in homeschool or private schools or die are removed from the cohort. They are not part of the calculated graduation rate four years later. Dropouts, students held back for academic reasons and GED students remain in the cohort and are still accounted for in the graduation rate.

In the graph below, each dot represents a district. The graph compares a school district’s graduation rate and how its cohort has changed over four years. Districts with higher graduation rates will land at the top of the graph. Districts with bigger drops in enrollment will fall more to the left, which based on records, occurs in most districts.
